Help with wheels

I would probably go with the 14x7 version of this wheel just because it will make your 70 series tires look a little wider and allow you to put 60 series tires on the back later if you want. Fourteen inch tires are getting harder and harder to find, at least they are here in the US.

Thank you Brian.

There are two sizes of the bolt circle.

4.25" and 3.75". I would think mine had the bigger one because of the disc brakes, would I be right?
